Answers:
K, as simple as possible...

If you don't have some type of internet nouns of your own, it's possible you could pick up a signal from someone else, provided:

A: They have a signal, and
B: it's close enough to your location, for the signal to be strong ample to work, and last:
C: They don't have a protected wireless network, meaning, you don't require a password to use their nouns.


It's kinda like listening to our neighbor's music, if the insulation is upright, or if it's 4 doors down, u probably won't hear it, well it's similar with wireless, if they own really good insulation, or the signal is located too far away, your computer won't "hear" it...
